Whilst not considered an essential mineral for plant growth, silica can provide many benefits for crops grown in any hydroponic media.  These include:

- assistance with the absorption and translocation of minerals;
- minimisation of the toxicity effect of other minerals;
- aiding plant structure and support by keeping plants erect and positioned for optimum light collection;
- increased resistance to many fungal diseases; and
- development of healthier, larger root systems.
